Description
Technical field
The utility model relates to power equipment partial discharge monitoring technical field, specifically, is power equipment partial discharge monitoring system.
Background technology
, always there is defect in various degree in various impurity, moisture, air gap etc. owing to containing in solid, liquid medium in conventional Electric Power Equipment Insulation.These defects are exactly the main cause causing power equipment shelf depreciation.Shelf depreciation brings great harm to Electric Power Equipment Insulation, because shelf depreciation service work is more numerous and diverse, the time is long, its power failure range advantageous design non-faulting element, and maintenance craft requires very meticulous, careless slightlyly just may cause repair quality problem.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides power equipment partial discharge monitoring system.
For achieving the above object, the utility model provides following technical scheme:
The utility model relates to power equipment partial discharge monitoring system, comprise high frequency sensors, data acquisition unit, data analysis unit, communication unit, described high frequency sensors is connected with data acquisition unit by concentric cable, described data acquisition unit is connected with data analysis unit by optical fiber, described data analysis unit is connected with communication unit by optical fiber, it is characterized in that, described communication unit comprises wave point and radio receiving transmitting module.
As further scheme of the present utility model, the terminal electric power system of described high frequency sensors and data acquisition unit adopts solar electric power supply system, comprises polycrystalline silicon solar plate, solar charging controller, battery pack.
Compared with prior art, good effect of the present utility model is:
The utility model can carry out the on-line monitoring of shelf depreciation at any time easily to operating power equipment, for the investigation of operation maintenance personnel to partial discharges fault provides important dynamic foundation, and basic analysis and judgement are carried out to the generation, discharge characteristic, magnitude variations etc. of apparatus local discharge, the analysis judged result of shelf depreciation is sent to pulpit by communication unit, notice pulpit personnel overhaul partial discharges fault in time simultaneously.
Accompanying drawing explanation
Fig. 1 is fundamental diagram of the present utility model;
Embodiment
The technological means realized to make the utility model, character of innovation, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
The utility model relates to power equipment partial discharge monitoring system, comprise high frequency sensors, data acquisition unit, data analysis unit, communication unit, described high frequency sensors is connected with data acquisition unit by concentric cable, described data acquisition unit is connected with data analysis unit by optical fiber, described data analysis unit is connected with communication unit by optical fiber, it is characterized in that, described communication unit comprises wave point and radio receiving transmitting module.
The utility model specific implementation process is as follows:
When power equipment partial discharges fault occurs, the fault current flowing through shaft tower makes high frequency sensors generation output signal and deliver to data collection control unit, data collection control unit complete A/D data conversion after by relevant data after data analysis unit completes data distinguish process again through wave point and radio receiving transmitting module, send electric network fault relevant information to master-control room by mobile communication network with short message mode, master-control room personnel take corresponding emergency repair measure after receiving failure message in time.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, therefore all changes be intended in the implication of the equivalency by dropping on claim and scope are included in the utility model, any Reference numeral in claim should be considered as the claim involved by limiting.
